Mayday, mayday, we have lost all power. We have a hole. We have two holes in the boat. Reporter: Listen to this distress call one pleading for help as the boat he and four others are aboard is rapidly filling with water. Grab our signal. We are going down. Reporter: The 30-foot boot 17 miles way from the San Diego shore losing power Saturday. The pump system unable to operate. Water weighing the vessel down and the boat leaning precariously to one side. No power and holes in the boat. Reporter: I didn't know if there was a giant hole or a pinhole in the boat but there was a problem. Reporter: The men on a deep sea fishing expedition able to radio for help firing an emergency flare in the air. We couldn't find anything because the bucket wouldn't fit so dunking water bottles in. Reporter: A good samaritan rushing to their rescue. 45-footer. Reporter: The coast guard moments behind using pumps to remove the water before towing it to safety. On the way back we were full of energy, full of zeal for saving lives. I won't forget these people. Roger that. Reporter: For "Good morning America," Brandi Hitt, ABC news, Los Angeles.
